PSG won just four of their last 10 Ligue 1 matches, while they exited the Coupe de la Ligue at the quarter-final stage and Champions League at the last 16, while also losing to Rennes on penalties in the Coupe de France final.

And Tuchel has made it clear that his side have to step up their performances next season if they are to continue their domestic dominance and challenge in Europe's elite club competition.

"We have to improve, it's clear. We have to play with even more intensity during the matches," Tuchel told PSG's official website.

"To be competitive at the highest level, it is essential. We will have to go in one direction, show it to the players, to the fans.

"We created something, but it's not over. So we have to keep going, keep working and improve our game. Some matches have been won, but not the way you want, not the game you want to play.

"To give everything must become a habit. But I could not change that alone. It will be necessary to be very strict towards our principles of game. It is important. We will all have to go in the same direction."
